I moved these functions to X86InstrInfo.cpp, so they are available from
another pass. In addition, this is a step toward resolving the FIXME to
move this metadata to the instruction tables.

This is the final step to make these two data invariance checks
available for non-SLH passes.

The other two steps were here:
